IMPRQVEMEN T IN LO0MS.

TO WHOM IT -MAY '.CONCERN:

' Be it known that we, THOMAS G. THOMPSON and BARCLAY BALLARD, ofRichmond, Indiana, have invented certain new and useful Improvements inIIau l-Looms and we do lhereby declare the followingtov be a. full,`clear, and exact description of the same, reference being had to thedrawings whielraceompany this specification,

and to the letters of reference marked thereon.

In the drawings our improved loom is represented in perspective.

The nature of our invention' consists in the construction of ahand-loom, simple, cheap, and eifective, capable of doing every varietyof work at a greatly reduced price,and not liable to get out of order byuse.

A A represents vthe framing of a hand-loom of ordinary construction, inwhich F F are the betten-posts, and E the race or cross-piece connectingthe posts F F, and all together forming the hatten. In most looms, thebottoms of the posts Fare connected by across-rail, which rests inbearings on the side rail A. In other looms, pins or short shaftsproject from each rail A, and enter holesfin the bottoms oi' the posts.These pins are liable to be bent, and often become loose, and thus causethe hatten to rest and workunevenly. The brackets K are made of metal,have al square opening in them to receive the free ends of the arms F.These arms are pivoted in these openings on pins J, that have bearing atboth ends in the bracket; and these pins or pivots serve for bearing forthe lay-arms, and are held securely in a true horizontal position, andinsure a properand even action of thelay. The hatten is so hung in thebrackets K K, that when it is thrown back to the herldle-franie B B, therace-board E has an inclination downward and backward from the operator,and this obviates the disposition or inclination of the shuttle in itstransit to iiy its track and break the warp. m m are guide-strapsattached to the open ends of the shuttle-boxes respectively, and servingto press the shuttle backward and downward when entering or leaving theshuttle-box. The shuttle-honestT N are each provided with vshuttle-headblocks, to which are attached the throwing-cords y g, to the centre ofwhich cords the handle G is secured, the right I and left motion ofwhich by the hand of the operator actuat'es the shuttle. The trcadles 12 S are operated by Vthe feet of the operator, and are constructed andhungin the ordinary manner, and properly attacheddto the heddles, whichare operated by the treadles aforesaid. The cloth-beam D is operated bya takeup lever, H, and the pawls 5 6 working a ratchet-wheel, (Z,secured to the end ot' the shaft or beam D. The warp-beam L is properlyarranged to rcvolvevin the back end oi' the upper side rails A A, and isprovided with a spur-wheel, J. The spur-wheel J'is rigidly attached tothe warp-beam L, between one of its heads andthe beam-bearing, andrevolves with the saine. The let-off lever I traverses the length of theside piece A, being pivoted thereto at z', und provided with a segmentat its rear end, which is fitted into the cogs ofthe wheel J, and isheld there b y the action of the .stop 'i'. v The warp, being wound uponthe warp-beam, is carried forward over the roller-shaft C, and throughthe harness and reed, and attached to tbc cloth-beain D in the ordinarymanner, and is tightened up by the operation of the take-np lever II on'the right hand oi' the operator, while with his left hand grasping' Ithe handle of the lever I, he raises it suieiently to let oil' the warpas may be required. The let-od' and the Vtake are thus at the control oftlieopcrator rigidly and exactly.

Among the advantages which we claim for our improved loom are,simplicity and durability of construction, being coniposed of fewerpieces, and produced at less cost than. any other hand-loom known to us;the brackets K K, as a. superior method of pivoting the lower ends ofthe hatten-posts; the arrangement and operation of the levers H and I,and their connections, for governing the tension of 'the warp thearrangement race, by which the shuttle is kept in fpinee during itstransit, and the use of the guide-straps m m as auxiliary thereto.

Having thusfnll-'y described our said improved loom, what we claim asnew, and desire to secure by Letters Patent, is

1. The brachctsK K, in combination witli the hatten-'posts F F, pivotsJ, and the side rails A A, all con- .strn'eted and arranged as hereindeseribed,

2. The combination of the warp-beam L, spur-wheel J, pivotcd let-*offlever I, rack z', stop T, cloth-beam D,

ratchet-wheel d, take-np lever II, and pawls 5 and 6, when constructed,airangcd, and operating as and for the purposes herein set forth anddescribed.
